Alrightly, usualy this would only happen for like 5seconds at 7am when its dead cold, and the car would work it out and be fine.. Just befor i went for a short trip and when stoped it hunted like hell, 800-1200rpm with the timing going all over the place 2-40deg, it took a while to work it out, gave it afew revs, what could be the reason of this? Also, my duty cycle for some reason is comming close to %100 but befor it wouldnt pass %85..

(usualy mods, pfc, fmic, exhaust, 12psi, tuned for 200rwkw) what could cause this problem? Any help appreciated..

check afm plug. something in the car has changed and the FC is trying to compensate around it. failing that, get the tune saved perform DATA INIT and idle self learn. i had this problem about 8 months (ish) ago and self learn idle fixed it spot on. then just copy the tune data back

      S1 Autech 260RS Wiring Diagrams

      Agreed, I've never seen a 260RS specific manual. As GTSBoy said it will mostly be stagea other than the engine loom https://www.hgeconsulting.com.au/stageaservicemanual.pdf

      You'lll likely have to make do with R33 GTR for engine/tranny stuff, and Stagea for the body. I don't know that there's even been an actual diagram seen in the wild.

      Haha, i kow right? Could have bought so many cars for the same amount of money (or less) but driving Unicorn gives you at least +1mln to style 😅. Like wise man said "life's to short to drink cheap wine and drive boring cars" 😉

      S1 Autech 260RS Wiring Diagrams

      By ARB26 · Posted

      Newbie here, proud owner of an Autech 260RS. I'm on the hunt for wiring diagrams specific to the 260RS, particularly S1. I've ran my eyes through R33, R34 Diagrams, there are some similarities, however continue to find incorrect wire colours and pins on connectors in the 33,34 diagrams.   I was hoping someone could point me in the right direction? I'd be happy to pay for the originals in Japanese. I can translate them, at least they would be accurate.   Any help please would be greatly appreciated, never heard an RB26DETT before let alone driven one, and I've got a spaghetti monster of goodness to sort out.   Cheers Benny
